salaah and wudhu questions

Salaams MuftiPlease advise on the following :1. If ghusal is made for any reason, and wudhu is part of this ghusal, to read namaz/quraan therafter, does the wudhu have to be made again as one was naked whilst performing ghusal?Is this accepted or should a seperate wudhu be made after whilst being clothed?2. Is wudhu that is made whilst naked valid?eg, after bathing, make a normal wudhu at the taps howver one is still naked?3. Can namaaz be read by wearing a long dress covering the ankles for a women but without wearing any pants?
